J'"ri)ni these ubservations it may be conchuled thai the insect norm- 

 ally passes some time after transformaticui in comparative inactivity, and 

 probably does not is<ue from the wood in which it breeds until at least 

 two weeks after airiving at maturity. 



A. viridicornis Sa}. — (3bserved on elm leaves June iitli — iSth. 

 A. viridi/rons is noted as occurring- on elm also (Ent. Am. vol. V, p. 31). 



A. cvanella Gory — I3red from chestnut twigs. May iith. 



A. quercata Fab. — Observed on lea\es of chestnut and chestnut 

 oak during June and July. 



Yox convenience I have assumed that the species of Anthaxia above 

 mentioned are distinct, though there are good reasons for the belief that 

 viridi/rons and viridicornis are se.xes of a single species, and cvanella and 

 quercata constitute in like manner another species. 



Chrysobothris feniorata Fab. — To the list of half a dozen trees 

 noted as being infested by this species I add hickory, having cut the 

 imago from the larval passages in the wood. It was taken during the 

 past season at Siaten Island on a log of white birch, May 17th and I 

 have no doubt it breeds in this wood also. 



C. deniipes Germ. —From the uniformity and frequency of the oc- 

 currence of this insect on pines, it is doubtfid if it breeds m any but 

 coniferous trees, although Harris (Ins. Inj. to Veg. p. 49) states that it 

 inhabits the trunk of oaks! 



C sex-signafa Say. — One specimen cut from a beech tree in which 

 it had bred. In the list previously referred to (p. 31) this species is 

 mentioned as having been beaten from pitch pine. 



C. azurea Lee. —Taken by INI r. A C. Weeks on dead sumach {Rhus 

 toxicodendron) on Long Island and Staten Island, N. V. in |une. 



Acnneodera culta Web, like other species of the family is peculiarly 

 a sun beetle. I have repeatedly e.xannned the flowers of Geranium ma- 

 culatuni in die shade without ever discovering a single specimen, while 

 the tiowers th.U were e.xposed to the sun fairly swarmed with the little 

 beetles. They eat the petals ol this plant and of the wild rose also. June 

 and ]ulv. 



Agrilus egenus Gory. — Hred in great numbers from the twigs and 

 smaller branches of the common locust tree {Robittia pseudacacia). The 

 larva" form mines under the bark, eating both baik and wood. Some 

 little time is required by the imago to issue from the wood. On one oc- 

 casion, May Sth, many specimens were observed with their heads, and 

 in some cases, thorax and anterior legs projecting Ax)m the bark, and 

 some were still to be seen in that position two days later. Of the beetles
